iscsi源代码 UNH的progect 有initiator端和target端的源码

#!/bin/sh
# 
# A template for setting up a connection to the target using SRP 
#
# Copy this file under /opt/unh/iscsi/conf/<TARGET-NAME> [the same <TARGET-NAME>
# should be used in /opt/unh/iscsi/conf/fstab.iscsi also, for consistency] and
# make the necessary changes detailed in the guidelines (below) and
# /usr/share/doc/unh-iscsi*/README.CONFIG.
# 
# GUIDELINES
# ----------
# The following environment variables are autoset by iscsi_connect
# and SHOULD NOT be re-defined by the user.
#
# HOST         - iSCSI Initiator Host HBA number 
# TARGET_NO    - Target (session) Number 
#
# Script should return success(0) or failure(1) back to iscsi_connect.
# PATH also includes /opt/unh/iscsi/bin.
#
# To run a target script on startup, set the execute permission
# /bin/chmod +x /opt/unh/iscsi/conf/<TARGETALIAS>
# 
# To not run a target script on startup, unset the execute permission
# /bin/chmod -x /opt/unh/iscsi/conf/<TARGETALIAS>
#
# DOCUMENTATION
# -------------
# For more information on iscsi_manage and iscsi_config, please refer to
# iscsi_config(8) and iscsi_manage(8).
#
# CUSTOMIZATION
# ------------
# Additional parameters can be set to connect to the target. For a complete
# list of additional parameters refer to  iscsi_manage(8).
# 
# The iscsi_config can also be used to set up multiple connections to
# targets or to make connections to specific LUNs (the default is to
# connect to all LUNs on the target). The complete features of the
# iscsi_config command can be found at
# /usr/share/doc/unh_iscsi*/ISCSI_CONFIG.
#
# CONFIGURATION
# -------------
# The following variables need to be defined by the user.
#
# <INITIATOR NAME> - A fully qualified iSCSI Initiator name as expected
#                    by the Target.
INITIATOR_NAME=

# <TARGET NAME>    - A fully qualified iSCSI Target name.
TARGET_NAME=

# <TARGET IP>      - Target portal's network IP address.
TARGET_IP=

# <PORT>           - Port number of the iSCSI Target at <TARGET IP>
#                    Default is 3260.
PORT=3260

#
#<LUN>		   - Probe ALL (0) LUNS or set to a specific number <1..14>
LUN=1

#
# NOTE
# ----
# The set of iscsi_manage and iscsi_config statments section below
# are considered bare minimum to connect to the target and should not be 
# removed (they can be modified, however).
